Scope Sequences in ActiveRecord

Recently I have been working on Helpful which is a support tool being built through the Assembly platform.

Internally we use UUIDs for everything but for user facing interactions we wanted nice integer id numbers. So what we want is an auto incrementing unique integer column.
